RELATED: Sound as a Weapon Part 3: Protection from Damaging Sounds Since you may not be able to increase distance, sound blocking and sound absorption are your standard choices for handling loud sounds.

There are essentially three ways to protect yourself from loud sounds - increase the distance between you and the sound source, find a way to block the sound pressure waves, or find ways to absorb or attenuate the sound. You should be aware of the effects loud sounds can make on your body. These kinds of sights precondition us to know what is possible.ĭuration of exposure to sound pressure is serious. The concussion from that explosion knocks the actor off his feet (simulated in the movie, of course).Ī scene in the movie “Lucy” shows the title character making a shrill sound so loud and penetrating it takes down all the other humans in a hallway.
The movie “Under Siege” shows an actor standing near an 8” battleship gun when it goes off. We begin to feel physical pain at 140 DB and can tolerate it for less than a second. Notice in Table 2 how fast the acceptable time exposure decreases as sound levels increase. This is why the government restricts how long you can work in loud environments without special headsets to protect sensitive eardrums. It’s when sounds become louder than 90 dB that hearing damage can occur. However, we are able to listen to 80 dB sound for more than 25 hours without harm. The 80 dB sound of a garbage disposal truck – can become noisy if the sound persists.
